Ah, but you *can* use some quite clever quoting to get that effect. E.g. this starts up python with /usr/bin/env and a -O argument: #!/bin/sh """"exec /usr/bin/env python -O $0 "$@";" """ Credit for this trick originally belong to someone else: I found this on some website, but I don't know where anymore. I'll leave it as a exercise to the reader to figure out how it works. :) James _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
